摘要
Abstract
Taking ammonia nitrogen as processing object, the paper examined removal efficiency of ben-tonite, zeolite and flyash respectively modified by hydrochloric acid, sodium hydroxide, sodium chloride to the ammonia nitrogen and preliminarily selected the better modified absorbents through jar test. Test results showed that under the conditions of the water temperature 25℃, oscillation frequency 100r/min, adsorption time 2h, removal rate of the modified absorbents to the ammonia nitrogen had certain enhancement , the removal effect of sodium chloride zeolite to ammonia nitrogen was the best.关键词
